Problem when Limited users use MS Office in XP pro

I have a machine with XP Pro on it, and I have three users.....me as Administrator; and two limited user.

Whenever I log in as either of the limited users and try to open any of the Office apps, the Windows installer kicks in, and I then receive an error 1706, that it cannot find the required files, and to check my network connection or that I have the CD inserted. Once I click okay, it goes ahead and opens up the application, and I can open files associated with that program.

What's the cause of the error, and how do I resolve it. Is this an Office problem, or an XP OS error?
